Safety Warnings
Power Supply Considerations

• The system ground is the power supply and chassis ground.
• Use the grounding lug to attach a wrist strap for ESD protection during servicing.
• Do not connect the DC return wire to the system frame or to the system-grounding equipment.
• Ensure that the DC return is grounded at the source side.
Guidelines for AC-Powered Systems
Basic guidelines for AC-powered systems include the following:
• Each chassis power supply has its own dedicated branch circuit.
• Ensure that the circuit breaker is sized according to the power supply input rating and local or national
code requirements.
• The AC power receptacles that are used to plug in the chassis must be the grounding type. The grounding
conductors that connect to the receptacles must connect to protective earth ground at the service equipment.
Prevent Power Loss
Use the following guidelines to prevent power loss to the device:
• To prevent input power loss, ensure that the maximum load on each circuit supplying the power is within
the current ratings of the wiring and breakers.
• In some systems, you can use an UPS to protect against power failures at your site. Avoid UPS types
that use ferroresonant technology. These UPS types can become unstable with systems such as the device,
which can have substantial current-draw fluctuations due to bursty data traffic patterns.
Determining power requirements is useful for planning the power distribution system to support the device.
Preventing ESD Damage
Ground this equipment. Use a green and yellow 6-AWG ground wire to connect the host to earth ground
during normal use. Statement 383
Warning
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD may occur when
electronic printed circuit cards are improperly handled and can cause complete or intermittent failures. When
removing and replacing modules, always follow these ESD prevention procedures:
• Ensure that the device chassis is electrically connected to earth ground.
• Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. To channel unwanted
ESD voltages safely to ground, connect the clip to an unpainted surface of the chassis frame. To guard
against ESD damage and shocks, the wrist strap and cord must operate effectively.
• If no wrist strap is available, ground yourself by touching a metal part of the chassis.
• When installing a component, use any available ejector levers or captive installation screws to properly
seat the bus connectors in the backplane or midplane. These devices prevent accidental removal, provide
proper grounding for the system, and help to ensure that bus connectors are properly seated.
• When removing a component, use available ejector levers or captive installation screws, if any, to release
the bus connectors from the backplane or midplane.

Safety Warnings
Guidelines for AC-Powered Systems

• Handle components by only their handles or edges; do not touch the printed circuit boards or connectors.
• Place a removed component board side up on an antistatic surface or in a static-shielding container. If
you plan to return the component to the factory, immediately place it in a static-shielding container.
• Avoid contact between the printed circuit boards and clothing. The wrist strap only protects components
from ESD voltages on the body; ESD voltages on clothing can still cause damage.
• Never attempt to remove the printed circuit board from the metal carrier.
For the safety of your equipment, periodically check the resistance value of the antistatic wrist strap. Maintain
the value between 1 and 10 Mohm.

Network Timing Interfaces
• BITS input or output—The BITS interfaces support clock recovery from either a T1 at 1.544 MHz or an
E1 at 2.048 MHz, configurable by software. BITS interface is provided through a standard RJ-48 connector
on the front panel.
• 1PPS input or output and ToD input or output—This shielded RJ-45 interface is used for input or output
of time-of-day (ToD) and 1PPS pulses. ToD format includes both NTP and IEEE 1588-2008 time formats.
The same RS422 pins for 1PPS and TOD are shared between input and output directions. The direction for
each can be independently configurable through software.
Use an SMB connector on the front panel for the following:
• GPS 10 Mhz input and output—10 MHz input for GPS Synchronization.
• GPS 1 PPS input and output—1 PPS input for GPS Synchronization.
External Alarm Inputs
The router supports four dry contact alarm inputs through an RJ-45 jack at the rear panel.
• Normally Open—indicates that no current flows through the alarm circuit and the alarm is generated
when the current is flowing.
Each alarm input can be provisioned as critical, major, or minor.
Console
The RS232 console port provides transmission (Tx), reception (Rx), and ground (Gnd).
Cisco NCS 540 Router Hardware Installation Guide

Cisco NCS 540 Router Overview
Network Timing Interfaces

USB Console
A single USB 2.0 Type-A receptacle on the front panel of the router provides console access to ROMMON,
Cisco IOS-XE and diagnostics. While it uses the Type-A connector, it operates as a USB peripheral only for
connection to an external host computer. This interface requires the use of a Type-A to Type-A connector
instead of a standard USB cable.
Use of the USB console is mutually exclusive of the RS232 console port. This interface requires the use of a
Type-A to Type-A USB cable.
Note
Online Insertion and Removal
The router supports the following OIR operations:
• When an SFP is removed, there is no effect on traffic flowing on other ports.
• When an SFP is installed, the system initializes that port for operation that is based on the current
configuration. If the inserted SFP is incompatible with the current configuration for that port, the port
does not become operational until the configuration is updated.
• Both power supplies are installed and active, the load may be shared between them or a single PSU could
support the whole load. When a power supply is not working or the input cable is removed, the remaining
power supply takes the entire load without disruption.
Power Supply (N540-PWR400-A and N540-PWR400-D)
The Cisco NCS 540 router supports two AC or DC power supplies, which power the router. The second power
supply ensures redundancy in the system. Both power supplies support hot swapping capabilities.
Fan Assembly (N540-FAN)
Cisco NCS 540 Router comes with 4 individual fan modules. Fans are located at the rear panel and support
hot swapping. Fan flow is supported only on the forward direction from front to back.
The system can function with a single fan failure but if more than one fan is faulty then the system shuts down.
